Turned on calculator and screen reads operating system not found install OS now

To transfer the operating system to the handheld, connect your handheld and computer with a USB Connection Cable and use TI-Nspire™ Teacher Software with TI-SmartView™ or TI?Nspire CX Student Software (Windows® / Mac®).
This is the link that will download the OS (it's free) to your computer:

If you dont have the TI Computer Link Software you must download it from the TI site. Once it is installed plug you device into the computer and run the program. Select your device using the button at the bottom right of screen. Once selected click help then check for handheld OS update then follow on screen instructions.

First of all you will need to erase your calculator by holding Home(house key)+enter+P and than the on button. Make sure the on button is the last button you press. Then, select option 2 to erase your operating system. Then, you need to obtain the operating system 2.0 for the calculator. Download and install that onto the calculator. It should install operating system 2.0. Once you do that, download and install operating system 2.1. This will allows you to upgrade your calculator to the latest version and get past the full bar loading screen. Let me know if you need anymore help.

First of all erase your operating system. Then, find and install operating system 2.0 first. Once you do that, you can download and install the latest operating system onto your calculator. It should finish the loading screen.

You must install your OS (Windows XP, Vista, Windows 7, etc....)
